Compared with existing technologies, this ventilation structure for highway tunnel construction uses a fixed frame, sliding rod, second locking post, fork, actuating post, and second spring. Actuating post moves the corresponding sliding rod via two forks, which in turn moves the corresponding second locking post and compresses the second spring, causing the two second locking posts to disengage from their corresponding second locking holes, making it easy for workers to quickly remove the filter plate for cleaning.

[0036] To improve maintenance efficiency, the connecting structure 5 includes a rotating rod 501 rotatably connected to one side of the mounting block 2. One end of the rotating rod 501 is fixedly connected to a toggle rod 502. Two elliptical disks 503 are fixedly connected to the rotating rod 501. A sliding column 504 is slidably connected to one side of each fixed plate 6. A push plate 507 is fixedly connected to one end of each sliding column 504.

Each second snap-fit ​​post 903 is slidably connected to one side of the filter frame 7 and is adapted to the corresponding second snap-fit ​​hole. When the actuating post 905 is moved, the actuating post 905 drives the corresponding sliding rod 902 to move through the two forks 904. The sliding rod 902 drives the corresponding second snap-fit ​​post 903 to move and compresses the second spring 906, so that the two second snap-fit ​​posts 903 are disengaged from the corresponding second snap-fit ​​hole, making it convenient for the staff to quickly remove the filter plate 8 for cleaning.

[0038] Working principle: Moving the toggle lever 502 causes the rotating rod 501 to rotate, which in turn rotates the two elliptical disks 503. The elliptical disks 503 push the corresponding push plate 507 to move, which in turn moves the corresponding sliding column 504 and compresses the corresponding first spring 508. The sliding column 504 then moves the corresponding moving plate 505, which in turn moves the corresponding first locking column 506, disengaging it from the corresponding first locking hole. This allows workers to quickly remove the air duct 4, improving maintenance efficiency. Moving the toggle column 905 causes the sliding rod 902 to move via the two toggle forks 904. The sliding rod 902 then moves the corresponding second locking column 903 and compresses the second spring 906, disengaging the two second locking columns 903 from the corresponding second locking holes. This allows workers to quickly remove the filter plate 8 for cleaning.
